摘　　要：主要叙述高功率二极管的理论模型和结构设计 ,采用基于引导磁场和相对论近似情况下的空间电荷限制流模型 ,对磁浸没无箔二极管产生的空心相对论电子束进行了动态数值模拟 ,研究了二极管几何结构及引导磁场对二极管束流特性的影响。The theoretical models and the structure designs of the high power diode are described in this paper. The insulator, the structure of cathode and anode, the guide magnetic-field are analyzed and calculated in detail. The space charge limited current model, based on guide magnetic-field and theory of relativity approximation, is used to simulate the relativity electron-beam and study the influence of diode structure and guide magnetic-field on the characteristic of foilless diode beam-current.
